FASTENER.

Application filed May 7, 1925.

This invention relates to temporary fastening means for securingwrappers about commodities which it is desirable to enclose within anenvelope or wrapper, and as here (.lisclosed, is shown in connectionwith the wrapping and temporarily securing of the burlap or fabricwrappers with which it is usual to envelop or wrap round bales ofcotton.

An object of the invention is to provide a. convenient and simplefastening means which may be attached toa wrapper, and, as the wrapperis fed through the press during the step of covering a' bale, willtemporarily hold the cover in snug condition about the bale ready forthe permanent sewing or securing of the wrapper.

In the drawings Fig. 1 is a view, somewhat diagrammatic, of a round balepress and a wrapper having an embodiment of the present inven tionapplied thereto, partially wrapped around the completed bale.

Fig. 2 is a diagrammatic view showing the action of the fastener as itpasses beneath the press roller.

Fig. 3 is a view in side elevation of the fastener on an enlarged scale,detached.

Fig. 4 is a view in plan of the under side of the fastener. I

Fig. 5 is a view in side elevation of the fastener taken at an angle of45. to Fig. 3.

Referring to the drawings in which like numerals indicate correspondingparts in the several views, indicates generally a press of any desiredtype designed for forming a round bale from a suitable bat of cotton.The formed bale is shown at .11 with the cover 12 partially wrappedabout the bale, said cover 12 being generally of burlap or othersuitable fabric, and passing to the press in a continuous sheet from thewrapper roll 13, disposed in proper relation to the press.

The bale 11 will, of course, be formed in the usual manner by feedingthe bat down the feed chute 141 to the rollers 15 of the press, and whenthe bale has been formed, the cover 12 will then be fed into the press,and, by continued operation of the press, wrapped around the bale untilit is brought to the overlapped position indicated at 16 in Fig. 2.

The continuous length of fabric coming Serial No. 28,752.

from the roll 13 will, of course, be severed at an appropriatepointbetween the press and the roll 13, after the bale 11 has beencompletely wrapped and the ends of the cover have been brought to theoverlapped position disclosed in Fig. 2.

In this position, the bale is completed,

the cover has been applied, and the covered bale is ready to be removedfrom the press.

It is necessary, however, to temporarily secure the cover 12 at itslapped ends, in order that when the bale is removed from the press, theexpansion of the highly resilient cotton will not displace the coveriand distort the compressed and symmetrical oale.

In my present improvement, this is accomplished by the use of thetemporary fastening device shown in detail in Figs. 3, 4 and 5.

The device, as there shown, comprises a fastener made up of the bodymember 17, which, will be seen from Figs. 3, 4 and 5, is comparativelythin and of polygonal shape, being shown as square. The body haschamfered, tapered, or rounded portions 18 on its top side at eachcorner. The purpose oi. these c-hamfered portions 18 is to enable thefastener to pass easilybetween the surface of the press rollers 15 andthe periphery of the bale without aifect-ing the relation of thefastener to the cover 12. EX- tending from said body memberat a pointsubstantially at the center thereof is a shank 19, having a conicalenlargement or end 20, which enlargement 20 is adapted to pierce thecover 12 and temporarily secure the overlapped ends of said covertogether.

The base portion 21 of the conical enlargement has square sides as shownat 22, which sides are formed by grinding off the base of the cone. Itwill be noted that the sides 22 are arranged at an angle with respect tothe sides of the body member 17, as clearly illustrated in Figs. 3, 4and 5. It will be noted further that the sides 22 terminate at theirmeeting ends in sharp points or barbs 23 which engage and se curely holdthe threads of the cover and preventthe fastening device from beingaccidentally withdrawn from the cover 12 after it has been once forcedthrough it. The

- base or under side of the conical enlargement presents a plane or flatsurface to the cover and is parallel to the under face of the bodymember 17.

In applying the fastener to the cover 12 as it is fed from the roll 13,the squared ranged with respect to the body member, is

also diagonalto the weave of the burlap, or other cover material, andthat the points or barbs 23 securely hold the threads and prevent thedisplacement ofthe fastener.

Bythe use of such a construction, it is extremely ditficult to removethe temporary fastener from the cover; in fact, the fastener cannot beaccidentally removed from the overlapping ends of the cover as shown at16, Fig. 2, after the roller 15 has once caused the enlargement topenetrate the cover and be maintained in position therein bytheengagement of the barbs with the threads.

I claim:

1. A fastener of the class described comprising a substantially flatbody member having its exposed surface chamfered at the corners thereof,and a reduced shank extending from said body member and having,anenlargement of substantially conical form, the base of saidenlargement being polygonal.

2. A fastener of the class described comprising a bodymember, and ashank extending from said body member having a conical enlargement, thebase of said on largement being substantially square.

3. A fastener of the class described comprising a body member, and ashank ex tending from said body member having a conical enlargement, thebase of said enlargement having cut away sides.

4. A fastener of the class described comprising a flat polygonal-shapedbody member having its exposed top surface rounded off at each corner,and a shank extending from said body member and terminating in a conicalenlargement, the base of said enlargement having straight sides arrangeddiagonally with respect to the sides of the body member. 5. A fastenerof the class described comprising a body member of polygonal form, and ashank extending from said body member having an enlargement of conicalform, thcbase of said enlargement having straight sides arranged at anangle to the sides of said bodymember.

6. A fastener of the class described comprising a substantially squarebody member, and a shank extending from the body member and having anenlargement of conical form, the base of said enlargement being providedwith straight sides, which are arranged at an angle to the sides of thebody member.

7 A fastener of the class described comprising a flat substantiallysquare body member having chamfered corners, and a shank extending fromsaid body member and ALEXANDER S, MACKEJZIE.
